What a great description! Absolutely right! Never really looked at it like that, but it is...! Imagine a little caterpillar dipped in color and allowed to wander all over the quilt top...or a snake..though those images could be disturbing to some I guess, ...anyway it is squiggles all over. Some modes of stippling also include the more graphic geometric stitching. Some quilt police would debate that. It is simply put...even ,consistent patterned stitching used to fill an area. These stitches be very close and often help to define. All over stippling is a true meandering appearance covering the entire quilt.
